Sinumerik Alarm 300752 Axis %1 drive %2 blocking frequency of setpoint current filter too high

Sinumerik Alarm 300752 Axis %1 drive %2 blocking frequency of setpoint current filter too high

Parameters:
%1 = NC axis number
%2 = Drive number

Definitions:
The blocking frequency of a current setpoint filter is greater than the reciprocal value of 2 current controller cycles (violation of the sampling theorem). (1/2*MD 1000*31.25 microsec)

Reactions:
– NC not ready.
– Channel not ready.
– Channel not ready.
– NC Stop on alarm.
– NC Start disable in this channel.
– The NC switches to follow-up mode.
– Alarm display.
– Interface signals are set.

Remedy:
The value of machine data MD 1210: $MD_CURRENT_FILTER_1_SUPPR_FREQ (blocking frequency of current setpoint filter 1) or MD 1213: $MD_CURRENT_FILTER_2_SUPPR_FREQ (blocking frequency of current setpoint filter 2) or MD 1216: $MD_CURRENT_FILTER_3_SUPPR_FREQ (blocking frequency of cur- rent setpoint filter 3) or MD 1219: $MD_CURRENT_FILTER_4_SUPPR_FREQ (blocking frequency of current setpoint filter 4) must be less than the reciprocal value of two current controller cycles MD 1000: $MD_CURRCTRL_CYCLE_TIME (current controller cycle). (1/2*MD 1000*31.25 microsec)

Program Continuation:
Clear alarm with the RESET key in all channels. Restart part program.
